rtc: isl12026: Drop "_new" from probe callback name

The driver was introduced when .probe_new was the right probe callback
to use for i2c drivers. Today .probe is the right one (again) and the
driver was already switched in commit 31b0cecb ("rtc: Switch i2c
drivers back to use .probe()") but the name continued to include "_new"
in its name.

To prevent code readers wondering about what might be new here, drop
that irritating part of the name.
